  • Page 44: Printer Mechanism Operating Principles

    This printer mechanism uses a drop-on-demand ink jet system similar to the one used on all other EPSON ink jet printers. However, the printhead in this system has been completely redesigned to make it more compact and to ensure a high level of reliability. The printer has two printheads: monochrome (black ink) and color (yellow, cyan, and magenta ink).
  • Page 45 Tc pulse. EPSON Micro Dot Printing Mode The Stylus 1500 has a special black ink printing mode called EPSON Micro Dot Printing Mode. This mode can be selected when using a special paper type (such as glossy or transparency).

  • Page 46: Printer Mechanism

    Operating Principles Printer Mechanism The Stylus 1500 printer mechanism is composed of the printhead unit; paper feed, carriage drive, pump, and push tractor feed mechanisms; and various sensors. The figure below shows a functional block diagram of the printer mechanism. Depending on the position of the carriage unit, the paper feed motor torque is transmitted to the paper feed, auto sheet feed, push tractor feed, or pump mechanisms via a disengage mechanism.

  • Page 47: Carriage Drive Mechanism

    Operating Principles Carriage Drive Mechanism The timing belt attached to the base of the carriage unit is driven by the carriage motor, causing the carriage unit to move along the carriage guide shaft from left to right or vice versa. The carriage drive motor in this printer is a 4-phase, 96-pole, hybrid-type stepping motor, allowing the printer to stop the carriage or change the carriage movement at any position.

    Operating Principles Platen Gap Adjust Mechanism Set the platen gap adjust lever, attached to the left upper side of the printer cover, to the appropriate position for the paper thickness. The platen gap adjust mechanism consists of the platen gap adjust lever, carriage guide shaft, and two parallelism adjust bushings. Switching the lever between positions 0 and + rotates the carriage guide shaft toward the front or rear.

The figure below illustrates pump operation. When the paper feed drive motor rotates backward (counterclockwise), the color pulleys in the wheel pump unit rotate in the direction of the arrow while squeezing the ink tube to push the ink out to the waste ink drain tank.

    Operating Principles Paper Feed Motor Driver Circuit The paper feed motor for this printer drives the following mechanisms: Paper feed Paper pickup Pump The UDN2917EB paper feed motor driver IC (IC15) outputs a constant current to drive the paper feed motor. The E05B12 gate array (IC2) determines the motor phase (PFAPH and PFBPH), phase current (PFA0/1 and PFB0/1), and current setting signals (PFV), and then sends the signals to the paper feed motor driver IC.

    Operating Principles Black Printing Common Driver Circuit The common voltage (VH) corresponds to characteristics of the specific black printhead installed. This value is stored in advance in the EEPROM on the C172 MAIN board by the host computer. (See Head Data Writing Operation in Chapter 4.) Gate array E05B16 (IC2) refers to this value when it outputs parallel data for voltage control signals (BHV0 - BHV5) to the common driver circuit.
